Which best describes a spontaneous process as it relates to the second law of thermodynamics? It destroys heat.
xz_007 [3.2K]

Having in mind that a spontaneous process is capable of proceeding in a given direction without needing to be driven by an outside source of energy, then it must occur naturaly. This is actually spontaneous. Also take into account that in order to define a spontaneous pattern we need to state  no work performed on the system or on the surroundings.

A charged particle isinjected into a uniform magnetic field such that its velocity vector is perpendicular to themagnetic field
Bumek [7]

Answer:

D) follows a circular path

Explanation:

This is because the magnetic force F on the charge, q due to the magnetic field B with velocity vector v perpendicular to it, equals the centripetal force acting on the charge.

So, F = Bqv = mv²/r.

So it follows a circular path.

If the net force acting on a stationary object is zero, then the object will A. remain at rest. B. accelerate in the direction o
ra1l [238]

The object will remain at rest

Newton's first law states that if a body is at rest or moving at a constant speed in a straight line, it will remain at rest or keep moving in a straight line at constant speed unless it is acted upon by a force.

Here net force is zero

An object with a net force of zero acting on it will remain at rest, if initially at rest, or it will maintain a constant velocity.

F=MA

Force F=0

Than Acceleration A=0

With zero Acceleration stationary object  will remain at rest.

Hence Remain at rest is the correct answer
